Title: Underwater communication equipment
Inventor: HIRAKAWA SEIICHI
IPC: G10L21/0324
Filed: 1989-06-02
Abstract: PURPOSE:To attain communication with stable sound volume and sound quality regardless of a shallow water depth by connecting a sensor detecting a change in a water pressure and sending an output signal in response to the change, and varying the amplification factor of an amplifier and the frequency characteristic or the like. CONSTITUTION:A pressure type sensor 4 is arranged, e.g. under water and subjected to a change in the water pressure attended with the water depth. Since an output of the pressure type sensor 4 changes with a change in the water pressure, the amplification factor and the frequency characteristic of the amplifier 2 are changed via a proper electronic circuit in response to the level of the output signal and the attenuation in the sensitivity and efficiency and the change in the frequency characteristic caused in the speaker 3 and the microphone 1 or the like due to the water pressure are corrected, thereby attaining the communication with nearly constant sound volume and sound quality even at the place of shallow or deep water depth.

Title: Selection circuit
Inventor: SAKURAI TETSUO
IPC: H01H47/00
Filed: 1977-11-25
Abstract: PURPOSE: Not to cause the memory state of the selected switch to change regardless of ON.OFF of the electric power input without recourse to the mechanical lock switch by attaching a non-lock switch with a non-volatile memory so as to cause the switch to memorize its state of operation.  
     CONSTITUTION: When one of non-lock switches SW1WSW5, for example, SW1 is selected and depressed, transistor Q1 is made ON so that the set winding S of latching relay RL1 is energized to set the relay RL1. Concurrently the reset winding R of remaining latching relays RL2, RL3 is energized so as to reset the relays RL2, RL3. As RL1 is the latching relay, it memorizes its set state regardless of suspension of the electric power. Therefore this state is never changed if it is again energized. Namely, the contact rL1 of the relay RL1 continues its closure. Accordingly, the selected output of switches SW1WSW3 can be utilized via contacts rl1, rl2, rl3.

Abstract: PURPOSE:To prepare the titled compound (some of which is novel) useful as a synthetic intermediate of alpha-cyanoacrylic acid ester, in high yield, by hydrocyanizing pyruvic acid or its ester under acidic condition at a pH of lower than a specific level. CONSTITUTION:The cyanhydrin of formula II (novel compound when R is alkyl, alkenyl or alkoxyalkyl) is prepared by hydrocyanizing pyruvic acid of formula I (R is H, alyl, alkenyl or alkoxyalkyl) or its ester under acidic condition at <=5pH. The hydrocyanizing reaction is carried out by using a cyanizing agent (e.g. hydrocyanic acid, sodium cyanide, etc.). By keeping the pH of the reaction liquid constantly to an acidic condition of <=5, the decomposition of the pyruvic acid used as the raw material can be suppressed, the produced cyanhydrin can be maintained stably, and the hydrocyanidation reaction can be carried out in high yield.

IPC: G06F17/28
Filed: 1991-05-16
Abstract: PURPOSE:To correctly translate a composite word without registering the composite word in a dictionary by forming the translation of the composite word. CONSTITUTION:A morpheme analyzing part 1 executes morpheme dividing processing or the like by means of a dictionary 5. A syntax analyzing part 2 obtains the information of an individual word and forms tree structure in accordance with a grammatical rule 6. At that time a part to be translated as a composite word is detected and processed by syntax analysis. A syntax conversion part 3 converts the tree structure of an input language into the tree structure of an output language. A morpheme formation part 4 translates the obtained tree structure in each note by means of a formation rule 7. Thus translation information corresponding to composite words is registered in the dictionary or another information storing part, a composite word in an original is recognized and the translation of the composite word is formed from the translation information of the composite word.

Filed: 1987-06-05
Abstract: PURPOSE:To obtain a thermal head capable of high speed printing with lengthened service life and being driven with low power, by forming an overcoat layer from a material where tungsten is added to SIALON. CONSTITUTION:An overcoat is formed from a material where W is added to SIALON. SIALON means silicon(Si)-alminum(Al)-oxygen (O)-nitrogen(N) compounds. The overcoat layer formed from a material where W is added to SIALON has good contact tightness against heating element layer in thermal head, and is hardly separated therefrom even if it is cracked due to biting of foreign matter during printing. Furthermore, thermal efficiency can be improved without sacrifice of high speed response. Preferably, W is added by 0.1-20 atomic % for the entire SIALON. The thermal head is prepared by forming the overcoat layer through sputtering, deposition, etc. Consequently, the thermal head can be driven at low power with high speed and lengthened service life, and the service life can be stabilized.

Filed: 1988-06-07
Abstract: PURPOSE:To generate character patterns for each country by a memory in the minimum quantity by referring to accessory information related to a character code and computing No.2-No.n character pattern addresses from a first character pattern address in response to an operation mode. CONSTITUTION:When a font code C1 is transmitted, a first character pattern address a11 corresponding to the font code is output from a pointer table 10. When a flag table 20 is read in response to the font code C1, accessory information f1 is obtained. When an operation mode at that time is represented by m1, an information value n1 corresponding to m1 in the accessory information f1 is output from the flag table 20. A character pattern address computing means 30 adds the information value n1 from the flag table 20 to the first character pattern address a11 from the pointer table 10, and computes a character pattern address a1n. Accordingly, a corresponding character pattern is read from a character pattern memory 40, and a required character pattern is generated.
